-Modulo Operator (``%``)
-=======================
-
-Calculates the `remainder <http://en.wikipedia.org/wiki/Remainder>`_
-when one integer is divided by another. It is useful for keeping a
-variable within a particular range (e.g.  the size of an array).
-
-Syntax
-------
-
-::
-
-    dividend % divisor
-
-Parameters
-----------
-
-**dividend**: the number to be divided
-
-**divisor**: the number to divide by
-
-Returns
--------
-
-The remainder of **dividend**\ /\ **divisor**\ .
-
-Examples
---------
-
-::
-
-    int x;
-    x = 7 % 5;   // x now contains 2
-    x = 9 % 5;   // x now contains 4
-    x = 5 % 5;   // x now contains 0
-    x = 4 % 5;   // x now contains 4
-
-::
-
-    /* update one value in an array each time through a loop */
-
-    int values[10];
-    int i = 0;
-
-    void setup() {
-        // no setup necessary
-    }
-
-    void loop() {
-      values[i] = analogRead(0);
-      i = (i + 1) % 10;   // modulo operator makes sure i stays between 0 and 9
-    }
-
-Tip
----
-
-The modulo operator does not work on floats.  For that, you can use
-the C standard library function `fmod()
-<http://sourceware.org/newlib/libm.html#fmod>`_.
